Objective To summarize the progress of biological indexes which could predict the efficiency of neoadjuvant chemotherapy for breast cancer. Methods Various related researches were collected to make a review. Results Many indexes linked to the efficiency of neoadjuvant chemotherapy for breast cancer according to several studies. According to many studies, indexes such as human epidermal growth factor receptor-2 (HER-2) gene, estrogen receptor (ER), progesterone receptor (PR), Ki-67, P53 gene, neutrophil to lymphocyte ratio (NLR), platelet level, and mean platelet volume (MPV) may have association with the outcome of neoadjuvant chemotherapy in treatment of breast cancer, and these factors maybe individual biomarkers to predict the efficiency of the treatment, but no coincident conclusion has been reached for these indexes. Conclusion The value of these indexes that predict the efficiency of neoadjuvant chemotherapy is not sure, further study need to be done to solve this topic.
Objective To have more insight into roles of growth differentiation factor-15 (GDF15) in digestive tumor. Method The basic and clinical studies on the GDF15 in the digestive tumors published were searched in the databases for summarizing the latest advances on this issue. Results The GDF15, a novel member of transforming growth factor-β superfamily, played the diverse roles in the progress of the various diseases. The increasing number of evidence indicated that the GDF15 was associated with the diagnosis and prognostication of the digestive tumors, eg: colorectal cancer, hepatocellular carcinoma, pancreatic adenocarcinoma, and might serve as a potential biomarker and therapeutic target for the multiple digestive tumors. Conclusions Current basic and clinical studies provide some evidences that GDF15 plays a role in digestive tumors. Further studies are needed to elucidate its roles and molecular mechanisms in different stages of diseases.
ObjectiveTo summarize the mechanism of action of programmed cell death protein 1 (PD-1)/programmed cell death ligand-1 (PD-L1) inhibitors, the application in breast cancer in recent years and the advances in the study of their bio-markers of effects. MethodRelevant literatures on PD-1/PD-L1 inhibitors and the study in the field of breast cancer were reviewed and summarized.ResultsIn recent years, the monotherapy of immune checkpoint inhibitors represented by PD-1/PD-L1 inhibitors or in combination with other therapies had brought new hope for patients with breast cancer especially triple-negative breast cancer (TNBC). However, only a small number of patients could benefit from breast cancer immunotherapy. The current researchers think that the efficacy of these drugs is related to PD-L1 expression in tumor tissue, tumor mutation burden (TMB), high level of microsatellite instability (MSI-H) and deficient mismatch repair (dMMR).ConclusionBreast cancer can benefit from the immunotherapy of PD-1/PD-L1 inhibitors, but formulating personalized medicine model, finding biomarkers that can predict efficacy and selecting patients with breast cancer who can benefit from it for targeted therapy are the new requirements in the new era of breast cancer immunotherapy.
ObjectiveTo understand the clinical value of centromere proteins (CENPs) in hepatocellular carcinoma and their influence on the malignant biological behavior of hepatocellular carcinoma, and to provide theoretical references for related research in this field. MethodDomestic and international databases were searched for relevant literatures on the study of CENPs in hepatocellular carcinoma in recent years to be analyzed and reviewed. ResultsA total of 11 CENPs closely related to hepatocellular carcinoma had been summarized, which were differentially expressed in hepatocellular carcinoma and correlated with prognosis. CENPs might regulate various malignant biological behaviors such as hepatocellular carcinoma proliferation, metastasis, apoptosis, and resistance to radiotherapy and thus participate in the development of hepatocellular carcinoma via multiple mechanisms. The roles and mechanisms of some CENPs in hepatocellular carcinoma remained unclear. ConclusionsCENPs play an essential role in the diagnosis, treatment, and prognosis of hepatocellular carcinoma. They are involved in multiple malignant biological behaviors of hepatocellular carcinoma and are expected to be potential therapeutic targets for hepatocellular carcinoma. However, their roles and mechanisms in hepatocellular carcinoma remain to be investigated.
